Hi Victor,

I searched (and found) some procedure, which was basically this:

-Package the current postgresql and install that in /tmp
-rename the current data directory
-delete current packages and install new ones
-initdb new database
-use some command to ‘copy’ (not cp ;) ) to transport old data to new

I don’t have the url currently available, but it wasn’t that hard to find either.
